I knew it was related, but I had assumed it did not rely on CSS. Again, I noted it was a naive view.
Granted, I probably view CSS with far more disdain than I should.
CSS is your friend
The cascading aspect is mostly a big L. As is the dream of user style sheets. All the more so from the obfuscated style names so many tools saddle us with.
Don't get me wrong, there are smart people working on css. That we decided, as an industry, to treat layout as a Rube Goldberg machination of interacting rules on a growing number of elements is not something you can easily overcome.
